Process

Pusher centrifuge is a continuous operating filtering centrifuge used for solid-liquid separation in the chemical and mineral industries. It has a unique design that minimizes moisture, impurity and crystal breakage in discharged cake, can perform feeding, filtration, washing and discharging in sequence at their full-speed running.

Application

HR pusher centrifuges are suitable for separating the suspension with solid particle size of more than 0.08mm, with the concentration rate of over 40%, and suitable for chemical industry, fertilizer, salt and alkali production.

Typical products:

Sodium chloride

Potassium nitrate

Potassiumchloride

Ammonium bicarbonate

Sodium sulfate

Potassium sulphate

Copper sulfate

Ammonium sulfate

Phosphate

Potassium carbonate

Polyethylene

Polypropylene

Nitrocellulose

Boric acid

Urea

Working Principles

The main motor drives the inner and outer baskets to rotate at the full speed, then feed the material through the feed pipe. Under the centrifugal force, the liquid is discharged out of the basket through filter screen and the holes of the basket, then out of the machine through the liquid discharge pipe, while the solid deposits in the basket as a ring layer of cake.

As the inner and outer baskets rotate at the same speed, the inner one, pushed by the piston, reciprocates axially and repeatedly. As a result, pusher plate pushes the cake layer from the inner basket to outer basket for further separation. A ring layer of cake being formed,while the outside section of the inner basket pushes the cake layer into the outer basket continuously, then discharge it through the slot by scraping.

Design Features

Advantages:

Continuous operation with large capacity

Ideal washing effect

Low moisture content of cake

Less solid content loss and crystal broken

Suitable for abrasion filtering cake

Limitations:
Minimum particle size≥0.08 mm
Material temperature≤80°C
Feed concentration of solids≥40%

Require stable feeding concentration(avoid over vibration)
